FEEDING DEVICE FOR DOUGH-MACHINES.

- Specification of Letters Patent.

Patented Nov. 26, 1907 T 0 all whom it may concern:

Be it known that I, PHILIP F. CARROLL, citizen of the United States,residing at J oliet, in the county of Will and State of Illinois, haveinvented certain new and useful Improvements in Feeding Devices forDough- Machines, of which the following is a specification.

This invention relates to improvements in means for feeding dough from ahopper into a receptacle where it receives further operations.

The especial object attained by my invention is the feeding of the doughwithout appreciable squeezing, it having been demonstrated that anyoperation on many kinds of dough which has the effect of forcing out thegases of fermentation, more or less impairs its quality.

In dough dividing machines and dough molding machines of well knowntypes, it is customary to feed the dough from the hopper in which it isplaced en masse, by two or more rollers, either smooth or corrugated,which draw the dough from between them, and this action has been foundto seriously impair its quality because of the expression of the gasesand the mutilation of the grain of the dough. My invention avoids thisdifficulty.

In the accompanying drawing, I have shown an adaptation of my inventionin the following views Figure 1 is a top-plan view of the hopper and aportion of a dough machine towhich my invention has been applied; Fig. 2is a section on the line 2-2 of Fig. 1.

Referring to the details of the drawing, 3 represents a portion of theframe of a dough dividing machine upon which is secured a loaf-formingchamber 4 and a piston 5.

6 represents a hopper of common form, and 7 a shaft which extendstransversely of the hopper, is suitably journaled in same and has asprocket wheel 10 secured on one end which may be driven from anysuitable source and in any well known manner. On the shaft is mounted aroller 8, and secured near the bottom of the roller, with its edge incontact therewith, is a scraper 9. It will be noted that the position ofthe roller is at one side of the bottom of the hopper and, compared withthe diameter of the throat of the latter, is of small cross-diameter sothat it projects but slightly into the passageway between the hopper andthe dough-receiving chamber 4. The roller 8, when rotated in thedirection indicated by the arrow in Fig. 2, engages a mass of doughplaced in the hopper with suiiicient frictional contact to draw thedough gradually down into the chamber I without exerting an appreciableamount of pressure, and therefore without expressing the gases orrupturing the grain or fibers of the dough.

I do not wish to be limited in the application of my invention to anyparticular class of dough manipulating machines, as it may be utilizedin any form of machine where it is necessary to feed portions en masseof dough to a chamber adjacent to the feed hopper, and where it isdesirable to avoid squeezing or wedging the dough between unyieldingsurfaces or contracted walls.

What I claim is 1. In a dough machine, a hopper adapted to receive amass of dough, a feed roller mounted at the discharge end of saidhopper, a scraper for said roller, a chamber adapted to receive thedough from the hopper, and a reciprocating plunger arranged to entersaid chamber at a point opposite said roller, and cooperating with saidroller to draw the dough into said chamber.

2. In a dough machine, a hopper adapted to receive a mass of dough, afeed roller of relatively small diameter mounted at one side of thedischarge end of said hopper, a scraper for said roller, a chamberadapted to receive the dough from said hopper, and a reciprocatingplunger arranged to enter said chamber at a point opposite said roller,whereby the plunger will cooperate with the roller in feeding the doughinto said chamber in advance of the plunger.

In testimony. whereof I affix my signature in presence of two witnesses.

PHILIP F. CARROLL.
